I'm migrating an AWS serverless platform at EPAM Systems to Kubernetes-based Spring Boot services, replacing DynamoDB and SQS with MongoDB and RabbitMQ.

At ABB, I migrated a terminal cash-in platform from IBM Integration Bus to event-driven Spring Boot microservices using Kafka and Oracle DB. I also built customer onboarding and sales services for customer creation, account opening, updates, and closures.

Previously at Topaz, I developed Java and Spring Boot microservices for its online betting platform, working across PostgreSQL, MongoDB, Redis, gRPC, Kafka, CI/CD, and containerized deployments. I also contribute to AssertJ, Quarkus, and RabbitMQ documentation.
